Saw some reviews on DHGate or Aliexpress reps and yes you really should stick to the TD section.
The Fact that they don't provide QC pics is shaky.
and you have no Idea what you're getting.
Most of them don't even tell the Factory.
I find Ali and DHGate best for clasp and bracelets/straps. If you look around, you can find the exact same deployant that the TDs sell at much lower prices. But for everything else watch related, stick with the TDs. You'll be much better off.
What you will get from Ali or DHGate are cheap reps from unknown factories, a random piece that may or may not be accurate.
My theory (can't prove it though) is that they use discarded parts from good factories, or they put together parts from cheap factories (no wonder the lume is sometimes different in the dial, needles and bezel altogether).
A TD from RWI will guarantee you good quality, buying from Ali or DHG is like putting your money on a casino's roulette.
